The first time that I travelled there and saw this complex in New Delhi I was impressed. I really loved it,but then I walked into one particular construction that is one of the several little buildings that make up the complex and I had this vision of trying to rebuild something inspired by it, becausepeople were really enjoying the site, walking on top, sitting on the stairs, and going up again. There was something I liked about the whole thing and I had this idea that it could be great.A building that you can place in nature, from which you could observe nature because it is built so that you can watch the stars.SB: The genetic code of the original observatory is conser...
